IMPROVEMENT IN BENCH-PLANES.

Specification forming partof Letters Patent No. 43,360, dated June 28, 1864.

.T 0 all? whom, it may concern:

Be it known that I, STEPHEN WVILLIAMS, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Smoothing- Planes; and I dohereby'declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side sectional elevation of my invention. Fig. 2 is a plan view of the same.

Similar letters of reference indicate like p irts.

I denominate my improvement the univer- 'sal smoothing-plane, because it belongs to that variety of planes in which theface is made changeable, so that it may be conveniently adapted to the planing of curved as well as straight surfaces By the use of my improvement surfaces that are convex, concave, or straight may be. easily worked, the face of the tool being readily changed from one form to another to suit the surface to which it is to be applied.

A is a hollow box, of the exterior form shown, made, in one or more pieces, of iron or other materials, receiving. the usual wedge, B, and plane iron 0, which passes obliquely through the box A, a nipple, a, at its front end to re ceive the'blow of the hammer during adjustment. composed of movable sections fitted together, some of them, I), made to conform at their uppcr endsto the shape of the-box A, againstrwhich said ends press, as shown. The blocks or sections D'D and the or blocks 1),

box A are bound together by an exteriorhoop or band,E, of metal, which incloses them. The end piece, b,.of the band E is made sufficient] y thick at its middle to have formed in it a screw-nut, through which a binding-screw, F, passes to press against the outer section-or By turning the screw block, D, as shown.

The remaining body of the plane is F the blocks or sections D D. and box A will all be firmly bound or pressed together, and, as their lower ends constitute the surface of the plane, .it is only necessary,- in order to change the form of the face of the plane, to vary the position of thesections and. box in respect to each other and then biudthem by the screw F. Upon eachalternate surface of the sections D D and box A there is a tongue and groove, 0 d, whichprevents lateral displacement of the sections, but allows of vertical adjustment. Upon the exterior of box A there are projecting tongues or ledgese e, between which the band E passes. These ledges preventthe displacement of the band E. The lower extremities of the sections D D and box A are made slightly rounded, so as to atford greater facility in moving the plane, pre- 'vent' the edges of the sections from catching on the surface of the work, 850.

The black lines in Fig. 1 show the plane as adjusted to plane a concave surface. The red lines show the position-of the parts when adjusted to plane a flat surface, and the blue lines show the adjustment for a convex surface.

- I do not confine myself to the precise form of parts herein shown, as that may be varied according to the skill of the maker; but,

Having th as described my invention, I claim as new and desire to secure by Letters Patcnt- '1. The construction of the body of the plane 'of movable blocks or sections, substantially in the'manner and for the purpose herein shown and described.

2. The combination of the movable sections D D,-indepen dent plane "bit-holder A, inclosing-band E, and screw F, all arranged and employed as described.
